I had been poking around the HVO earthquake map and saw several small earthquakes just off the coast of Kalapana (where the lava had been pouring into the sea until last weekend). I tweeted a bit with Ron Schott (@rschott) about these quakes, and I think this could be related to bench collapses. As the lava pours into the sea, it cools - and forms an oversteepened slope or cliff. The quakes were a bit deep for this (10 km), but these are small quakes, so it could be related to problems in data resolution.

There was another fairly strong pair of quakes (3+) early this morning, before the tsunami, and the distribution of quakes still appears clustered around Kalapana.

Here's the whole-island view. You can see the flurry of seismic activity from the Kamoamoa event. It's still not enough data to really say what's going on, but I do find it interesting the majority of recent seismic activity has shifted to the coast (for now). If you will allow this paleobiologist to speculate on why - my first guess would be that there is some settling and "relaxing" related to the cessation of flow down the pali and into the ocean at Kalapana. I don't see it as foreshadowing new eruptive activity - but I could be totally wrong, I guess. It's happened before.
